摘要：The present invention relates to for manufacturing poly function castor acidesters polyalcohol with primary hydroxyl end group. The invention further relates to thepolyether polyols that poly function castor acid esters polyalcohol can obtain accordingto the present invention to generate and the polyalcohol. This method comprises thefollowing steps: a kind of condensation polymer ricinoleic acid) until 0 mg KOH/g ＞ ofhydroxyl value and 60 milligrams of KOH/g of ＜ are to realize; The product obtained instep a) with reaction step b), reaction product, comprising carboxyl, the product obtainedin step a), the general formula (1) with epoxides, wherein R1 is hydrogen, alkyl or arylresidue, with that 80 weight % of ＞ ＜ to 100 weight % of specification, the total amount(1) relative to epoxides is used, ethylene oxide, reaction are to carry out amine in thepresence of a catalyst as catalyst.
